Elantra HD (2006-10) :: Alarm Keeps Going Off At Random
May 6, 2012
I have had my 2010 Elantra for about 2 months now, and 'all of a sudden' the car alarm starts going off - lights, beeps, at random. I have read a few places it has to do with a 'hood switch' - so where do I find it and what do I do with it once I find it?
Dealership has not been too friendly so far (not surprising - it IS a dealership), if I can find a quick and easy (and cheap) fix I can handle myself, I would rather do that. I prefer NOT to disable the alarm as I do want it to work.

I have read all the answers about the alarm going off at random times, mine just started tonight and dealership is closed. Is there anything that I can do to keep it from going off and waking the neighborhood?

First time here with my 2008 Elantra. (Bought new - Now 140,000 miles) Just started having a problem. Car alarm going off by itself?? Would a low battery in the remote cause that? Where would I go to find info?

Recently I took my car in for an oil change, & after that when I lock my car it doesn't always make the beep noise to let me know the alarm system is armed.
A little while after that, my alarm started to go off randomly. This happens at random times, all my doors are closed and we even took the car in to get checked(they checked the wires or something I believe because they thought it had to do with my aftermarket remote start)
I've read somewhere about people saying it could have to do with my hood switches? But truth be told I'm not very good with cars.

I have a 2008 Hyundai Elantra. When it's windy out the alarm keeps going off. Especially if the vehicle has been locked with the remote. If I manually open the vehicle and lock it manually the alarm is fine. I have had it to the dealer and they say the system is fine and that the sensors are fine.

So my factory car alarm has started going off by itself ; had to unhook horn wiring.
Bad hood switch issues are talked about ; seemed a little flaky when checked with meter so I changed it out, only $15. Hood pad already was made higher as a first try at fixing problem.
Still having alarm tripping sometimes. I read somewhere about the door lock actuators having a contact that tells alarm system when they are locked.
So I may have a faulty power lock assembly on one of the four doors. I have tried to open them when locked but they don't open. How to I tell which lock switch is bad , they are all pricy but the drivers rear is cheaper.

We moved to a new home two months ago.My 2009 elantra alarm randomly goes off only between 9:30pm and 8:30 am and only when in my garage or driveway. Dealer "adjusted hood sensor" and it still activates. Seems the issue must be in my garage as didn't happen prior to moving and happens no where else. I disconnected the garage remote wireless sensor tonight to see if that could be culprit.

So the situation is my battery died on my car and whenever I go to jump it the alarm goes off as soon as the cables connect. I let it sit for a minute and the alarm goes off for a period then turns off, then it starts going off again then turns off repeating this. The car wont turn over and I can't figure out how to turn off the alarm. How to get it to jump/turn off the alarm while it charges? I wont take it to the dealer to get it fixed unless its 100% something I can't do at home.

I have a 2008 Elantra SE. The anti theft alarm gets triggered for no reason on occasion. At first I thought it was only on rainy days, but now it happens in full sun as well.
I don't need the alarm, as nobody pays attention to them anyway. Is there a fuse I can remove to disable it?

I recently brought my 2000 chrysler sebring in because the alarm was going off at random times (3:00am). Also when I was driving the interior lights would turn on and off and the dash readout would say "DOOR" as if I had opened the door, there was a relay clicking sound under the dash and the car would also try to relock the doors. This was an intermittent problem, occasionally the car would be fine for a while then the show would begin. I took it to a local Chrysler dealer and they diagnosed the problem to be the BCM or Body Control Module.
My conclusion is that this whole problem was caused by a shorting door switch and that either they misdiagnosed the problem and when the new BCM did not fix the problem they found the real problem in the door switch or they just scammed me from the start. I think the "part exchange program" is a scam. Why don't I get the part back or why don't I get two prices, one if I exchange the part and one if I don't.
Could a faulty driver door switch damage a BCM? (I never heard of this before. In fact another dealer told me all he needed was the VIN to see if the part was in stock).

The factory 'Security System' aka alarm, in my 2000 Honda Accord EX goes off randomly. When this happens the horn sounds and lights flash for several minutes at a time. This can happen several times in one day and then not happen again for days or weeks. The owner's manual says that the security system is activated when the doors are locked and will sound an alarm if a passenger door, trunk lid or hood are opened while the system is activated. The system is deactivated by using either a key or the remote transmitter to unlock the doors. My mechanic tried to disable the hood latch switch, but this caused the alarm to sound continuously. How to fix the problem or disable the security system?

I have a 2012 Santa Fe and the front map light fixture was where my issue started. I believe from what I read that the diode had gone bad because the map lights would work if the light button was pressed, but not if the door button was pressed. At that point, the only issue I had was the light now working when the door opened. So, I ordered a replacement part and tried to install it today. It was harder to get the old one out than last time, but it came out no worse for wear and I unplugged the old map light fixture. I plugged in the new one and it did not work at all. I checked the wire and it looked fine, the prongs and they were fine and tried it again... nothing.
Now, the back seat dome light and trunk dome light don't work either. (with the new map light plugged in or not) Old one back in and still nothing. Checked the manual for the fuse that is supposed to control those lights and it is fine. I got frustrated because it made no sense and gave up for the night. (no light is even plugged in where the map light goes for now) I come in the house and now every hour or two (when I lock the car) the alarm sounds for no reason. The alarm button won't shut it off either, I have to hit unlock and it stops. (3 times in the last 5 hours now) So, I have decided to leave it unlocked for now. So far, so good. BUT, I need to lock my car when I am out without the alarm sounding and I need my dome lights working. Everything else with / in the car seems to be normal.

I bought a 2002 elentra and didn't know there was an alarm on it. For some reason was activated well I was in the store yesterday and I can not turn it off or start my car w/o it going off. I have tried unhooking the battery and resetting it as instructed by others but still keeps going off. I do not have a remote for it. How do I disable the alarm so I can drive my car again?

I just drove my 2005 Hyundai Elantra from California to Pennsylvania without a problem. Once I arrived in Pennsylvania I took my car in for a state inspection. About 24 hours later my car alarm kept repeatedly going off. Eventually it stopped. When I tried to start the car it was dead. About 3 days later I had the car jumped. It ran fine. About 3 days later the car alarm randomly went off. I turned the alarm off and ran the car for 30 minutes and it was fine. About 24 hours later the car alarm randomly went off again. I turned it off and started the car. It ran fine. I checked the hood switches which was suggested in another post and they appear to be okay. There also doesn't appear to be any water around the battery.
What else could be causing this problem? Do you think the mechanic who performed the inspection could have hit something--my mother has had problems with them causing new problems after fixing old ones? Could it be the alternator? Could drastic temperature changes cause the problem--it does seem to happen when it goes from bitter cold to warmer, or is that just a coincidence?

We have been fighting a misfire code for about a year now and I'm pretty sure I finally found the cause. Last Spring the car died on the road and we had it towed to a local service center where they said the fuel pump was bad...this was the 2nd in about 2 years (previous owners doc). We had it replaced and the car was fine but as mentioned had a random misfire code that would come and go. In the last month the car has left us stranded several times and then started after a few hours or a day. While checking the connection to the fuel pump with a meter and test light I verified the pump was getting power correctly to the 5-pin connector but would not start. I unplugged the connector and the 1st 2 pins in the harness connector were damaged and probably burnt.
I cleaned it and applied dialectic grease and plugged it back in turned on the key...fuel pump primed and then the car started and ran fine. It then started to randomly turn on and off but not enough to stall the car. I wiggled the connector and the it I could make it run or shut off. Obviously the connector is bad and the contacts are intermittent. While driving the vibrations would move it just enough to make it cut on and off and more than likely cause a misfire code and sometimes stall the car. My problem now is I can't find a replacement connector/pigtail for the harness connector anywhere including the dealer. Where can I get a new connector for the 5-pin fuel pump harness connector? I have found a MAF replacement connector that looks very similar but not 100% sure if it's the same.

My alternator recently died and I took my car to a shop to have it replaced. Since receiving the car back, I've noticed that the car seems to jerk at random while shifting. It seems to happen most when shifting from 1st to 2nd. This problem didn't exist before I had my car maintained. Any chance this is related to the work done and is something easily fixed or is it just coincidental timing?
It's a 2004 Hyundai Elantra, at 120k miles,,,

I got my oil changed and tires balanced Saturday at the local shop around the corner. Now my alarm goes off randomly and when I use the clicker thing to lock the car, the horn doesn't make the beep sound it used to on the the second click. It never did this prior to having the oil changed, but how could that have anything to do with the alarm? I need to figure out how to make it stop, it's waking me (and my neighbors) up at night, and I have to keep leaving where ever I am to go out and see if the dang thing is going off again, which it is about half the time.

I have a GLS 2011 and since wednesday my car alarm seems to be working one out of five time. The doors locks but no horn chime and no corner lights flashing.
Checked all the doors and the hood and everything's closed. Also checked with my backup remote and nothing.

Picked up my brand new elantra last week, however alarm was not working properly. It arms ok (i.e., horn chirps after two clicks, lights flash etc)...but when we tried to test the alarm (as part of my delivery inspection), nothing happened. We tried opening door without key, opening from a half open shutter etc.
Dealer promised to resolve issue, they've been good so far, but it's worrying me a bit, brand new car, I shouldn't have to think of these issues and take my car and leave it in the dealer garage for a few days for them to diagnose this.

I have 2011 Elantra and been loving the car, getting great mileage. Recently I started hearing this ticking randomly while driving. Sometime during reverse, at random stopping. It is a single tick and it goes away.
